COLLAPSIBLE DISPENSING TUBE Filed May 12, 1959 ATTO RN EYS Patented July 9, 1940 UNITED STATES PATENT OFFICE 2 Claims.

This invention relates tocollapsible dispensing tubes and more especially to closures for such tubes.

An object of this invention is a closure structure which includes a cap adapted when screwed on tightly to seal the tube and when rotated approximately a quarter turn from such sealing position to open a passage through which the contents of the tube may be discharged.

According to this invention the collapsible tube is provided with an externally threaded neck. or spout having a substantially diametrically arranged barrier extending across its outer end and forming two apertures the area of each of which is less than one-half the cross section of the dis-" A cap is threaded onto said neck down tightly to register with. the barrier and seal i the tube. However, when the cap is turned back a quarter turn it brings the slot into register with the two apertures thus providing a discharge passage. Initially a sealing disk is provided in the cap and closes the slot therein and also limits the extent that the cap can be screwed onto the neck. The user first unscrews the cap from the neck, extracts the sealing disk, and then screws the cap back'onto the neck, thus making it ready for use as above described.

Other objects, novel features and advantages of this invention will be apparent from the following specification and accompanying drawing wherein:

Figure 1 is an exploded view of a collapsible tube closure embodying the invention.

Figure 2 is a side elevation, partially broken away, showing the sealing disk in place.

Figure 3 is an endview withthe sealing disk removed and the cap screwed down tightly.

Figure 4 is a section on the line 44 of Fig. 3.

Figure 5 is a View similar to Fig. 3 with the cap rotated a quarter turn.

Figure 6 is a section on the line 6-6 of Fig, 5.

In the drawing a collapsible tube I B of standard construction is provided with an exteriorly threaded neck II at the outer end of which is provided a substantially diametrically arranged barrier I2 at either side of which is provided an aperture I3. An interiorly threaded cap I4 screws onto the neck II and is provided with a diametrically arranged slot I5. A sealing disk I6 is initially placedin the cap I4 to engage the end of the neck I I to seal the tube until such time as it is desired to make use of its contents. Such sealing disk is shown in Fig. 1 and also in Fig. 2 the disk is shown in its sealingposition. The

thickness of the disk I6 limits the extent to which the cap I4 can be screwed down on the neck I I.

When it is desired to make use of the contents of the tube the cap I4 is removed from the neck by unscrewing it in the usual manner and the sealing disk is extracted. The cap is then re placed and screwed down into the position shown in Fig. 4 in which the slot I6 registers with the barrier i2 to prevent discharge ofthe tube contents. Rotation of the cap I5 through a quarter degree turn brings the slot I6 crosswise of the barrier I2 as shown in Figs. 5 and 6, thus putting the apertures I3 into communication with the slot I6. The contents of the tube Ill may now be discharged through a passageway thus provided by collapsing the tube in the usual manner.

. After as much as desired of the contents has been discharged, the cap I4 is screwed down on the neck II as far as it will go thereby bringing the slot I8 again into registry with the barrier I2 and sealing the'tube.

While the preferred embodiment of the invention is as has been above described, it is to be understood that other modifications are contemplated. However, in such modifications the neck or spout will be equipped with a barrier arranged flush with the end of the neck or spout to partially close the same and the cap will be provided with an aperture or slot which registers with the barrier when the cap is screwed down tightly thereby sealing the tube and which communicates with the open portion of the neck or spout when unscrewed slightly, thereby providing a dispensing passageway.

I claim:

1. In combination, a collapsible dispensing tube having an exteriorly threaded discharge spout with a diametrically arranged barrier extending across its end and forming two apertures, and an interiorly threaded cap on said spout, said cap having a diametrically arranged slot adapted in one position of said cap on said spout to align with said barrier and in another position to be in com-,

munication with said apertures.

2. In combination, a collapsible dispensing tube having an exteriorly threaded discharge spout with a diametrically arranged barrier extending across its end and forming two apertures, and an ALBERT JOHN VAN SCOYOC.
